  • 融合RGB-D图像,基于深度图实现坑洼物理深度测量。
  • YOLOv8nSeg在检测精度上表现最佳,深度估计误差仅2.96厘米。
  • 模型在边缘设备上部署可行,适合城市道路智能巡检场景。

坑洼检测及其严重程度评估仍是城市基础设施管理中的重要挑战,延迟维修会直接导致车辆损伤、道路事故和维修成本上升。现有自动化方法依赖2D RGB图像,无法测量坑洼的物理深度。本文提出一种深度感知坑洼检测框架,对比了五种架构:YOLOv8n、YOLOv8nSeg、YOLOv9t、RTDETR-L和RTDETR-X,基于RGB-D传感器融合进行检测与深度自动测量。采用自定义离线增强管道模拟恶劣道路监测条件。所有模型在PothRGBD数据集上训练(80%训练,20%验证),并使用精确率、召回率、mAP@50、mAP@50_95进行评估。深度图先通过RANSAC地平面正交校正消除相机俯仰影响,再将零值传感器像素转为NaN后计算统计量。YOLOv8nSeg达到最高mAP@50(0.9556)和mAP@50_95(0.6758),深度估计最准(2.96厘米),采用像素级Dseg算法。YOLOv8n推理最快(3.6毫秒)。RTDETRX检测置信度最高(92.70%)。重要发现:即使完成完整RANSAC正交校正,边界框模型仍高估坑洼深度0.16至0.21厘米,表明路面包含偏差是结构性而非校准误差。

原文摘要 · Abstract (English)

Pothole detection and its severity measurement is still an important challenges in urban infrastructure management, where late maintenance directly contributes to vehicle damage, road accidents, and escalating repair costs. Existing automated approaches depend on 2D RGB images and cannot measure physical depth of potholes. In this paper, we present a depthaware pothole detection framework and then compare five architectures: YOLOv8n, YOLOv8nSeg, YOLOv9t, RTDETRL, and RTDETRX for RGB-D sensor fusion-based detection and automated depth measurement. A custom offline augmentation pipeline is used here to simulate adverse road monitoring conditions. All models are trained on the PothRGBD dataset with an 80% training and 20% validation split and evaluated using Precision, Recall, mAP@50, and mAP@50_95. Before measuring the depth data, all depth maps are corrected for camera tilt using RANSAC ground-plane orthorectification and all zero-valued sensor pixels are cast to NaN before any statistic is computed. YOLOv8nSeg achieves the highest mAP@50 of 0.9556 and mAP@50_95 of 0.6758 with the most accurate depth estimate of 2.96 cm with the pixel-precise Dseg algorithm. YOLOv8n achieves the fastest inference at 3.6ms. RTDETRX achieves the highest detection confidence at 92.70%. An important finding is that even after full RANSAC orthorectification, bounding box models overestimate pothole depth by 0.16 to 0.21 cm compared to pixel precise segmentation masks. This confirms that the pavement inclusion bias is structural rather than a calibration artifact.
